VISIBLE LIGHT CATALYST FOR REMOVING SULFUR-CONTAINING COMPOUNDS IN FUEL OIL, AND PREPARATION AND USE THEREOF

摘要

Disclosed is a visible light catalyst for removing sulfur-containing compounds in fuel oil, consisting of a metal M_I selected from one of Pt, Pd and Au, a metal M_II selected from one of Ru and Ir, and BiVO₄ support, the mass ratio of M_I+M_II to BiVO₄ is in the range of 1:5000 to 1:50, and the mass ratio of M_I to M_II is in the range of 1:50 to 50:1. The catalyst can achieve a removal rate of more than 90% for thiophenic sulfur under mild conditions using oxygen as an oxidant and using a visible light source, without the oil being excited. A preparation method of the catalyst is also disclosed.
